Connecting alarm pin inputs

For alarm panels that provide „Positive applied‟ or „Positive removed‟ communicator outputs, the

unit‟s input pins can be wired directly to the Alarm panel.

Figure 20 - Alarm panel with Positive Applied or Removed communicator outputs

For alarm panels that have open collector communicator outputs (sometimes referred to as

„Negative Applied‟ outputs) an additional 10K pull-up resistor will be required to be connected for

each input pin.

an additional 10K pull up resistor for each pin

Note: Ensure the 0V of the alarm panel is Commoned to the 0V of the Redcare Secure unit when

separate Power Supply Units are used.
